DRV8870DDAR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 36V for reliable operation.
  • The sense resistor value depends on the motor current and the desired current sense accuracy. A general guideline is to choose a sense resistor value that results in a voltage drop of around 0.5V to 1V at the maximum motor current.
  • The EN (enable) pin is used to enable or disable the driver. When EN is high, the driver is enabled, and when EN is low, the driver is disabled. You can use the EN pin to control the motor's operation or to implement a shutdown function.
  • The DRV8870DDAR has a built-in overcurrent protection feature that limits the current to a safe value. However, you can also add external protection components, such as fuses or PTC thermistors, to provide additional protection.
  • The DRV8870DDAR can operate up to 100 kHz, but the maximum operating frequency depends on the specific application and the motor's characteristics.
